Development

pip is a volunteer maintained open source project and we welcome contributions of all forms. The sections below will help you get started with development, testing, and documentation.

You can also join #pypa (general packaging discussion and user support) and #pypa-dev (discussion about development of packaging tools) on Libera.chat, or the distutils-sig mailing list, to ask questions or get involved.
